Bathroom Wiring Adventures

We just got back from my mom and dad's house, where we stuffed ourselves on crappie, bluegill, and catfish. Healthy eating it wasn't, but I've been very good for awhile now. One of the twins spent this afternoon ice fishing with my dad; the other one gets to go tomorrow, while I have to take tickets for a wrestling tournament. So what did I do today? I wired the new bathroom upstairs. Does it work? You'll have to wait until the last slide to know for sure:*

*That was a lie; you must know I have to tell you. Everything works; all the outlets, the exhaust fan, and both sets of lights. I'm feeling rather smug. I had to wire it all to an existing circuit, but when the new breaker box goes in, that junction will be broken up and everything in this bathroom will go to a breaker that doesn't affect any other circuit. Currently the wiring in this house is a spiderweb, but this makes three rooms that are wired logically and according to international code, each ready to be connected to its own breaker.

I have a(nother) ceiling-fan project due this spring-time, the current and ancient squirrel-cage exhaust fan is sounding like a Pratt & Whitney...

In slide 4 it looks like you used individual wires that were not made into a cable, such as the romex that you used every where else. This is a violation of the National Electrical Code and not safe. I would redo that run. You don't want to take chances with electrical wiring.

Don, I'm so light now that I take my weight fully clad, often while holding dishes of food! And I'm still below 150.

From what I remember of the National Electric Code (NEC) I concur with PJohanon. The NEC doesn't allow individual wire runs outside of enclosures or conduit unless you use a jacketed cable like romex.

And did you use a GFCI protection device for the receptacles?

The individual wires are rated for the temperature inside the light/fan fixture. No cable I could find was; the insulation on the outside was always rated much lower. Romex insulation definitely does not qualify; it doesn't come close to meeting the temperature rating for the fixture.

What's the unsafe condition there? Is the thought that one wire might be pulled loose or crimped apart from the others? Can I cable it myself by taping, shrink-wrapping, or the like? It's oversize for the application--it's 12 all the way to the fusebox--but I don't want to take chances I don't have to take.

The good news is that all the outlets are GFCI and they do trip.
